How to use "GFLIB_sqrt_x16"

[Gildarai]

I develop SW on s12zvml with Codewarrior for MCU 11.1.

I want to calculate 'sqrt' fastly.

I found "GFLIB_sqrt_x16" function in gflib.h. But it might be could not find definition.

Here is messege

"Description Resource Path Location Type
Symbol GFLIB_Sqrt_F16 in file [MY DIR]\main_c.obj is undefined Gen3K_Application_NoBoot C/C++ Problem

There is no problem use "GFBLIB_Cos".

What can I use for this?

Best Regard.

Hi,

1) You want to use  sqrt so I suppose you have opened your project with float arithmetic possibilities. If not then it is easier to create new project and copy there files from older one than rebuild project for float arithmetic.

2) I suppose this is what you did
